AI Technical Summary

Benefits of technology

The patent describes an apparatus and method for providing immersive media content to multiple receivers. The apparatus acquires a representation of the content using a plurality of tiles that cover the representation. These tiles are then transmitted to each receiver, where they are used to present the content to the user. The technical effect of this invention is that it allows for the efficient and effective delivery of immersive media content to multiple users.

Problems solved by technology

Delivering multiple 3D objects may increase the bandwidth requirements and require tight synchronization of the playback of the volumetric objects.
However, some applications require a fast reporting for which such numbers are detrimental.

Embodiment Construction

[0033]Embodiments of the present invention are now described in more detail with reference to the accompanying drawings, in which the same or similar elements have the same reference signs assigned.

[0034]In streaming applications the 360° video data for the entire 360° video is provided by a server towards a client, e.g., over the air by a broadcast / broadband transmission or over a network, like the internet, using HTTP, and the client renders the received video data for display. Thus, the entire video content is provided to the receiver. In video communication applications, for example, video conferencing or virtual reality, VR, applications such as online gaming applications, in general only a part of a scene of the 360° video is presented to a user at the receiver, e.g., dependent on a viewing direction of the user. The client, on the basis of the viewing direction, processes the entire video data so as to display to a user that part of the scene of the 360° video corresponding t...

Abstract

An apparatus for providing immersive media content to a plurality of receivers is described. The apparatus obtains for a representation of the immersive media content a plurality of tiles, the plurality of tiles covering some or all of the representation, and, for some or all of the plurality receivers, transmits to each receiver one or more of the tiles, the one or more tiles covering at least a viewport associated with the respective receiver.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application is a continuation of copending International Application No. PCT / EP2020 / 078277, filed Oct. 8, 2020, which is incorporated herein by reference in its entirety, and additionally claims priority from European Application No. EP 19 203 077.3, filed Oct. 14, 2019, which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention relates to the field of immersive media.
